Изобретение относитс к электроизол ционным жидкост м, примен емым в качестве пропитываюпдих материалов в бумажных конденсаторах .This invention relates to electrically insulating liquids used as impregnating materials in paper capacitors.
Известны электроизол пионные жидкости на основе хлорированных углеводородов и дифенилоксида. В состав жидкости введено 20-50% хлорированного дифенилоксида и до 100% хлорированных дифенилов. Диэлектрическа проницаемость ее 5,8, температура замерзани -50°С. Такие жидкости имеют пониженное значение диэлектрической проницаемости .Known electrical insulating fluids based on chlorinated hydrocarbons and diphenyloxide. The composition of the liquid introduced 20-50% chlorinated diphenyloxide and up to 100% chlorinated biphenyls. Its dielectric constant is 5.8, the freezing temperature is -50 ° C. Such liquids have a lower dielectric constant.
С целью устранени указанного недостатка предложено в состав электроизол ционной жидкости вводить нитродихлордифенил при следующем соотношении компонентов . %):In order to eliminate this drawback, it has been proposed to introduce nitrodichlorodiphenyl in the composition of an electrically insulating liquid in the following ratio of components. %):
Нитродихлордифенил37-70Nitrodichlorodiphenyl37-70
Дихлордифенилоксид20-30Dichlorodiphenyloxide20-30
Хлорированные углеводородыChlorinated hydrocarbons
Остальноедо 100The rest is 100
В качестве хлорированных углеводородов может быть использован трихлордифенил или смесь его с трихлорбензолом.Trichlorodiphenyl or its mixture with trichlorobenzene can be used as chlorinated hydrocarbons.
Использование предлагаемого состава электроизол ционной жидкости позвол ет повысить значение диэлектрической проницаемости дл до 8, а дл КЛ 65Н до 6,5 ПО сравнению с 5,8 дл известных жидкостей.The use of the proposed composition of an electrically insulating liquid makes it possible to increase the value of the dielectric constant for up to 8, and for CL 65N up to 6.5 PO, compared to 5.8 for known liquids.
Пример 1. Дл получени диэлектрической жидкости смешивают 6 об. ч. (67 об. %) нитродихлордифенила, 2 об. ч.Example 1. To obtain a dielectric fluid, 6 vol. including (67 vol.%) nitrodichlorodiphenyl, 2 vol. h
(22 об. %) дихлордифенилоксида и 1 об. ч. (И об. %) трихлордифенила в аппарате с мешалкой при 25°С. Полученную смесь пропускают через колонку, заполненную активной окисью алюмини , при 120°С и затем фильтруют через керамический фильтр (размер пор 4,5-8 мк) при 120°С в вакууме.(22 vol.%) Dichlorodiphenyloxide and 1 vol. hours (And vol.%) trichlorodiphenyl in the apparatus with a stirrer at 25 ° C. The resulting mixture is passed through a column filled with active alumina at 120 ° C and then filtered through a ceramic filter (pore size 4.5-8 microns) at 120 ° C in vacuum.
Пример 2. Диэлектрическую жидкость КЖ-65Н получают по примеру 1 путем смешени 10 об. ч. (37 об. %) нитродихлордифенила , 8 об. ч. (29,5 об. %) дихлордифенилоксида преимущественно с температурой застывани (-55) -(-60°С), 1 об. ч. (4 об. %) трихлордифенила и 8 об. ч. (29,5 об. %) трихлорбензола .Example 2. Dielectric liquid QOL-65N was prepared as described in example 1 by mixing 10 vol. including (37% vol.) nitrodichlorodiphenyl, 8 vol. including (29.5% by volume) dichlorodiphenyloxide predominantly with a pour point (-55) - (- 60 ° C), 1 vol. including (4 vol.%) trichlorodiphenyl and 8 vol. including (29.5% vol.) trichlorobenzene.
Свойства полученных диэлектрических жидкостей в сравнении с известной ДЖ-50 приведены в таблице.The properties of the dielectric fluids obtained in comparison with the known J-50 are given in the table.
